MOP-WRINGER.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed April 30. 1907- serial No. 371.192.

To all whom it may concern:

Be it known that I, JOHN J. MCDONALD, a subject of the King of GreatBritain, and a resident of the city of Port Madison, in the county ofKitsap and State of Washington, have invented certain new and usefulImrovements in Mop-Wringers, of which the following is a specification.

My invention relates to improvements in devices of the above type andhas for its primary object the provision of a comparatively simpleconstruction which can be readily attached to a bucket and operated inan efficient manner with but little effort on the art of the operator.

ith the above and other desirable objects in view, to be referred to asthe description progresses, the invention resides in the construction,arrangement and combinations of parts hereinafter described and succinctly defined in the appended claims.

Referring now to the accom anying drawing, in which like numerals ofreference indicate like parts throughout the several views: Figure 1 isa view in top plan of my improved mop wringer. Fig. 2 1s a section takenon line 22 of Fig. 1, and Fig. 3 is a view in perspective of the resentinvention shown in position on a buc et, the latter beshown by brokenlines.

n carrying out my invention I provide a main frame 1 which is curved toconform to the interior curvature of a bucket and provided with suitablecatches or clips 2 adapted to engage over the upper edge of the bucket(see Fig. 3) for securing the said frame in position, and one of thesecatches or clips is preferably provided with a set screw- 3, as c earlyshown.

The rear end portions of frame 1 are bent inwardly to form yielding orresilient supports 4 on which is pivoted for vertical swinging a frame5, carrying a rotatably mounted roller 6. I

Reference numeral 7 indicate forward yielding or resilient supportssecured to the main frame, said supports being formed integral with aroller frame 8, havin a roller 9 rotatably mounted therein. R01 ers 6and. 9 act conjointly to wring the mop which in operation is passedtherebetween and by reason of the supports 4 and 7 the rollers are heldin yielding engagement with the mop so as to be ca able of being forcedapart should any part 0 the mop which is of greater thickness than theremainder be encountered.

Frame 5 is provided with a pair of stops 10 which are adapted to engagein notches, provided in the upper edges of supports 7, for limitingdownward movement of frame 5 and reventing any lateral movement thereof.

11 the present showing, frame 5 comprises opposite side bars connectedby a cross bar 11 and to the outer or free portion of said frame'ahandle 12 is pivoted. This handle is of suitable length to permit of theoperator grasping the same and swinging the frame 5 and holding saidframe down, while he draws the mop from between the rollers to effectwringing thereof, as is obvious.

In operation, the mop is placed on roller 9, when frame 5 is elevated asshown in Fig. 3, then said frame is lowered until roller 6 holds thesaid mop firmly against roller 9, when the mop can be drawn from betweenthe rollers. This operation, can obviously be repeated a number oftimes, but as I have found in practice, with the exerting of but littlepressure on frame 5 through the medium of handle 12, the mop will besufficiently wrung after having passed once or twice between therollers. m

The wringer is simple in construction and can be readily attached to andremoved from a bucket, so that frequent changing of the water in thebucket can be easily effected when the wringer is removed from thebucket.

- Having thus fully described my invention, what I claim as new anddesire to secure by Letters Patent of the United States of Amer- 1ca,is:

1. A mop wringer comprising a frame having free end portions bentinwardly to form yielding supports, a roller frame pivoted to saidinturned end portions of the first named. frame, a second roller frame,means to yieldingly support said last named roller frame on said firstnamed frame, and stops on said first named roller frame arranged toengage said means when said roller is in its lowered position.

2. A mop wringer comprising a substantially U-shaped main frame, aroller frame having yielding end portions and being yieldingly connectedthereby to the main frame within the latter, a swinging roller framepivoted to the end portions of the main frame, and rollers journaled insaid roller frames.

3. A mop wringer comprising a main frame conforming to the contour ofthe interior of the bucket and having yielding free end portions, aroller j ournaled in aframe connected to the main frame, and a rollerframe provided with a roller and being pivoted to said yielding free endportions for swinging move ment toward and away from said firstmentioned roller.

4. A mop wringer comprising a main frame having yielding free endportions, a substantially U-shaped frame provided with a roller andhaving out-turned yielding ends and be ing yieldingly secured by saidends to said main frame within the latter, a swinging frame pivoted tosaid free end portions of the main frame, and rollers journaled in saidU- 15 shaped and said swinging frames.

Signed at Seattle, Washington this 18th day of April 1907.
